CBS Radio: We've Cut 5% Of Workforce

CBS Radio, a laggard unit that says it's
turning around, has laid off "or declined to restaff" about
5% of its workforce in recent months.
MediaPost:

Rather than a sudden round of cuts, much of this trimming
happened slowly over a number of months. Altogether, it means
about 400 positions have been eliminated, the largest such
reduction since previous CEO Joel Hollander laid off 115
staffers in July 2006.

MediaPost also notes that other radio biggies are cutting back:
Emmis Communications has laid off 46, and Clear Channel's radio
group has ordered a hiring freeze, and has cut research and ad
spending through the rest of the quarter.

All of that makes sense -- radio is a stagnant industry, and the
ad market is uncertain at best. But we are a little stumped: If
400 workers represent 5% of CBS Radio's workforce, that means CBS
had previously employed some 8,000 people -- or an average of 57
workers for each of its 140 stations. Even factoring in a large
national corprorate HQ, sales staff, etc, that seems like an
awfully high headcount. Are we missing something?
